Yeah, this seems unavoidable. After a bit of discussion with Eric this morning, we came up with a cleaner design. A protocol knows only about format (not layer). A strategy knows about layer. A strategy can be used to trigger requests with a format - and the strategy supplies callbacks. In the case of read, the strategy callback expects to receive a list of features. All a moving target at this point. Good to have discussion on what things should look like. Tim > >> I've started putting stuff up in an "almanac" sandbox.
